' T o all wiwin it wia/y concern." i

, WELL and CARLy P. ASTROM, 'citizens ofthe Beit known that we,' MUNsoN-H. TREAD- Uni-ted States, oresiding at New York, in the county of NeWYOrkandl State of NewYork,

and EastOrange, county of Essex, and State .of New Jersey, respectively, have invented .f'cert'ain new and useful improvements. inl Dumping-Cars, ofnwhich the following is a llull, clear, and exact specification.

This invention `relatesto dumping cars,

'and lias'particular reference to cinder cars or the like wherein a tilting and bodily movable car'body is'mountedto be dumped in opposite directions from a central lupright ,position, as may be desired.

More' particularly, the invention c'oin-prisi-is apo'Wei`- actuated dumping cai' having a sin- 'gle cylinder and piston-of a'stroke egii'al to .p

'th'e'bodily movement in 'either direct/ion, the

cylinder beingbodily movable from one side to the otherof ythe car frame according toothedirection in whichl the` car body is to be `dumpedi By such an arrangement'it is possible to .provide a cylinder actuated dumping car in .Which tliecyli'nd'er will not project outside the permissible of the mechanism is effected.- As" herein shown, the car body is supported on trun- -nionswhich carryn gears engaging fixed racks carried on the car frame, of well kno w'n construction', and the piston'rod ofthe cylinder 'engages one trunnion, to move the car bodyI in one or the other direction from the central. position according'to the position of the cyl- -inder at one orthe othervside of the center.

The cylinder is itself mounted to swing v ertically on a'rack from one to the other side of the car frame when .it is desired to dump onadiferent side, and flexible or adjustable duid-pressure connections are provided for the cylinderin either position.

4. The invention will be more readily understood 'in' connection with the' description of .the'accompanying drawings, Wherein Figure 1 represents an. end view of a .dumping .carembodying the invention, and Fig. 2 represents a detail planview'of one of the trunnions.

. The carframe comprises the iisfualiiinder" frame carried by endfbolsters 1', the under frame not being herein shown, and 1s suported at the ends on trucks which Will'not g as these e particularly described herein,

distance from the rails,. and also a saving in Weight and simplification y theother may be arranged according to particular necessities rlhe holsters 1 each have a stationary rack 2 and a track 3, and the car body 4, lpreferably secured to a bail 5 which is provided lwith triinnions 6 at dianietrical points. Rigidly secured to the trunnio i 6 are gears 7 adapted to mesh with the i'ac is 2 (at each endet the car body) and rollers 8 which roll on'the tracks 3, the parts thus far described-.being of a well known construction.

ln order to actuate the car body a cylinder 9 havingpiston 1.0 and a Jpiston rod ll engaging the trunnion 6, is Zprovided, so that when lluid pressure is admitted' at one end lof the cylinder the piston will be moved to the other Erica;

end, and thereby the car b'ody moved laterally and simultaneously tilted. l In the position slioyvn infthe drawings, Ithe car body is in left; It is desirahlein Cars of thisutype, .that provision be made for dumping the car body at either side, as may be desired, and to this end, the cylinder 9 is niovably mounted so 4that it can be shifted from the right side as shown inthedraivings, to the left side Where-` car vbody tgthe right. In

by t`o dump the order tof accomplish this, l is-prov one of the holsters frame 12'having tfvo racks 13 guiding tracks 14, this frame, as herein shown, extendingl 'transversely of 4the-rar trame from .o ne side to the other. The cylinder 9 when inoperative position is support/ed 'on trun- `nionblocksl which rest in *unnion blocks carried by the bolster 1, at the ends ofthe curved frames, so that lthexcylinder is/firiiily Supported at opposite sides. i

To shift the cylinder 9 from one side to the other, there ris provided. ats-tub shaftj16 on which are niountedrollers 17 andgears 18, 19, the gear 18`meshing With the rack 13 and the rollers 17 rolling on frames 12 as the cylinder moves ogr from one side to thejither. kIn Orderto revolve the gear l'18, thegear 19 meshes ivithajgear 2 0 mounted` on a short shaftj21, Which can be turned'by the hand crank 22 vto roll the gear' 18-,over the rack 13 and thereby lift the cylinder from one side to this movement not changing the position. ofthe piston 10 'forthe reason that the ra fk '13 has as its center the' center of the4 trunnion 6. Fastening means may be used if 'desired for locking the Ositionto 'be tilted -and/ discharged `to the ided with an upWardly-cuivelslotted ico cylinder in the 'trunnion blocks, though ordinarily the weight fof the, partswill be sufficient iiohold the cyl- 110.

I inder, as there `is nomoment'tendingtolift/ nected by suitable-ll" it'. The -cylinderfg.is provided with p1 es 26,

27 leading to opposite ends and will 'e convalves with eL-source fr; uid pressure, su'ch as steam, air,` ortfhelke', manner, these` partsfnot being shown herein as they do not form a part of this'invention.

It is-thou ht that the o erationwillbe obsA vious' from t e foregoing lescription, it being@ understood that When it is desired 'to shift the f cylinder from-one side to theother the crank 22 "Willbe operatedl to cause "the lgear .18 to ride on the rack 13 and lift the cylinderfrom 1 5 one side tot-he other. Suitable checking'devices for Ichecking the movement, ofthe car 'bodyas' it approaches the .ends may be pro-l vided and it' Will of course be understood that the under frame Will be 'providedwith the usual end cou lingsin order to permit a num" ber of carsto e gathered into a'train.

^ actuating the car bo y, and means `whereby Modifications and changes Will be made in the speciiic construction `Without departing from the scope of the invention.

' Having thus ydescribed ourinve'ntion, We de# clare that what We claim as newf' and'desire,

to secure by Letters Patent', is

1`. The combination y:ith a car body 'mounted to' move laterally in 'either dire-ction fromv a central osition, `of a-motor for said motor can-be swung vertically about the point of applicationy of power from one side to the other to reverse the operation of the car body.

2. The combination With a tilting and lat-i.
